What is a loan?

A loan is a sum of money a lender provides to you (the borrower) with the expectation you will repay the principal plus interest over a defined term. The principal is the amount you borrow; the interest rate is the cost of borrowing expressed as a percentage; the term is how long you have to repay. Loans create a contractual relationship: the lender supplies funds now, and you agree to scheduled repayments, fees and any security arrangements.

Understanding loans helps you decide whether borrowing is the right move for purchases, business investment or bridging cash flow. This guide explains common loan types, how interest and fees work, what lenders assess, how to compare offers, and the consumer protections that apply. For a deeper dive on interest mechanics see How interest rates work.

Main types of loans

Loans come in many shapes. Below are the main categories you're likely to encounter, with typical uses and characteristics.

For more on personal borrowing options see Personal loans and for home borrowing basics see Home loans. If you're choosing vehicle finance, read about finance lease or novated lease where relevant.

How loans work: key features explained

Understanding key loan features helps you compare offers and predict total cost.

Principal: the loan amount you receive.

Interest: the fee charged on outstanding principal. Interest can be fixed (rate locked for a set period, giving predictable repayments) or variable (can move with market rates, e.g., changes in the cash rate).

Comparison rate: a standardised way to compare loan costs that combines the interest rate and most fees. It's useful because headline rates can be misleading.

Term: length of the loan. Longer terms lower repayments but usually increase total interest paid.

Repayments and amortisation: regular instalments that pay interest and part of the principal. Over time the interest portion falls and the principal portion rises. Lenders and comparison tools typically provide an amortisation schedule you can review.

Redraw: ability to access extra repayments you've made on some variable-rate loans.

Offset account: a transaction account linked to your home loan that reduces interest by offsetting the loan principal with your deposit balance.

Security / collateral: an asset the lender can seize if you default. Secured loans (e.g., mortgages, car loans) usually have lower rates due to reduced lender risk; unsecured loans rely on creditworthiness.

When lenders advertise an interest rate, always check the comparison rate and the Product Disclosure Statement (PDS) for fees and features.

Costs and fees to watch

Interest is usually the biggest cost, but fees add up and change the true price of borrowing. Common fees include:

• Interest charges: charged daily or monthly on the outstanding principal.
• Comparison rate: not a fee, but a metric that incorporates interest and major fees.
• Establishment / application fee: one-off fee to set up the loan.
• Ongoing or account-keeping fees: regular charges that increase cost.
• Valuation fee: for secured lending (property or vehicle valuation).
• Discharge / exit fee: charged when you fully repay and close a loan.
• Early repayment or break fees: apply when you repay a fixed-rate loan early; can be significant.
• Late payment fees and default interest: penalties for missed payments; default can lead to legal action and repossession.

Real-world example (illustrative, Jan 2026): a $10,000 personal loan at 9% p.a. with a $100 establishment fee and $10 monthly account fee over 5 years.

• Interest paid ≈ $1,000
• Fees ≈ $100 + ($10 × 60) = $100
• Total cost ≈ $1,800 (comparison rate captures similar effect)

Ask lenders to show the comparison rate and a total cost schedule. For guidance on consumer protections and responsible lending rules see ASIC's credit resources.

Eligibility and what lenders assess

Lenders assess your ability and willingness to repay. Typical criteria include:

• Credit history: defaults, late repayments and inquiries affect your score. See ways to Improve your credit score.
• Serviceability / income test: lenders calculate your net income less living expenses and other debt commitments.
• Employment stability: full-time or permanent employment and length of service help; self-employed borrowers need business financials.
• Living expenses and other obligations: lenders will review declared and assessed living costs.
• Loan-to-value ratio (LVR): for secured loans, LVR = loan amount ÷ asset value; higher LVR may need mortgage insurance or attract higher rates.
• Identification and verification: photo ID, proof of address, bank statements.

Typical supporting documents include recent payslips or tax returns (self-employed), 3 months of bank statements, photo ID (driver licence, passport), proof of deposit or equity, and property contract or vehicle invoice (if applicable).

Different products have different thresholds; business loans require additional financial statements and cashflow forecasts.

Comparing loan offers — what to prioritise

When you compare lenders, focus on net cost, flexibility and fit for your needs.

• Compare the comparison rate, not just the advertised rate.
• Check all fees (establishment, ongoing, discharge, redraw).
• Confirm repayment flexibility: extra repayments, repayment frequency, redraw access, offset accounts.
• Fixed vs variable options and any switch costs or break fees.
• Minimum/maximum loan amounts and repayment structures.
• Loan term — estimate total interest for alternative terms.
• Lender reputation, service quality and turnaround times.
• Request the Product Disclosure Statement (PDS) and an amortisation schedule for your scenario.
• Ask for example comparison rate calculations for your loan amount and term.

If comparing business options, consider specialised products such as equipment finance or invoice finance.

How to apply: step-by-step

A typical application flow:

1. Prepare documents: ID, proof of income, bank statements, asset valuations or invoices.
2. Pre-approval (for mortgages or larger purchases): get conditional approval based on preliminary checks.
3. Submit application: complete forms, authorise credit checks, upload supporting documents.
4. Assessment: lender verifies income, performs credit check, may request a valuation (property/vehicle).
5. Offer and acceptance: lender issues a loan contract or letter of offer; read the PDS and terms.
6. Settlement/funding: once conditions are met, funds are released or the loan is settled.

Be ready to answer questions about living expenses and other debts.

Pros and cons: when a loan makes sense

Pros

• Enables large purchases or investments now rather than later.
• Can be tax-effective for business or investment borrowing — check ATO guidance and get tailored advice.
• Secured loans often offer lower interest rates.
• Predictable structure for budgeting when fixed-rate or fixed-term.

Cons

• Interest and fees increase total cost; long terms inflate interest paid.
• Secured loans put assets at risk if you default.
• Variable rates expose you to market movements.
• Short-term high-interest loans can cause debt spirals.

A loan makes sense when expected returns (personal utility, business profit, mortgage rate vs investment yield) outweigh costs and risks, and you have a realistic repayment plan.

Alternatives to taking out a loan

Consider these alternatives before borrowing:

• Savings: delay purchase until you've saved to avoid interest.
• Family or peer lending: can be lower cost but formalise terms to avoid disputes.
• Buy-now-pay-later (BNPL): useful for small purchases but can affect cashflow and credit; check terms.
• Community lending and no-interest loan schemes (NILS): for eligible borrowers.
• Budgeting, expense reduction and building an emergency fund.
• For business cashflow: consider options such as invoice finance or a line-of-credit rather than term loans.

Choose alternatives that match urgency, purchase size and your ability to manage repayments responsibly.

Red flags and consumer protections

Red flags

• Very high advertised rates for short-term loans (e.g., payday-style five-figure annualised rates).
• Vague fee schedules or refusal to provide a Product Disclosure Statement.
• Pressure to sign quickly or promising guaranteed approval without checks.
• Requests to provide passwords or transfer money to third parties.

Key consumer protections

Responsible lending obligations require lenders to assess your capacity to repay. Consumer protections include:

• ASIC's guidance on credit and responsible lending practices
• The National Consumer Credit Protection Act, which sets the legal framework
• ASIC MoneySmart for practical borrowing checklists and loan information
• Reserve Bank materials explaining how the cash rate influences variable loan costs

Where to get help

If a lender won't provide clear terms or a PDS, treat that as a strong warning sign. For support:

• Contact your lender immediately if you can't repay
• Seek a financial counsellor through free community services
• Consult ASIC MoneySmart resources for borrowing guidance

Quick worked example

Example (illustrative, Jan 2026): You borrow $15,000 over 5 years at a fixed 8.5% p.a. annual interest.

• Monthly rate ≈ 8.5% / 12 ≈ 0.7083% (0.007083)
• Number of payments = 60
• Monthly payment ≈ $119 (using a standard loan calculator or the lender's amortisation schedule)
• Total repaid ≈ $11,140 → interest ≈ $1,140

If you reduce the term to 3 years at the same rate, monthly payments rise but total interest falls. Always ask for an amortisation schedule from the lender illustrating total interest and principal over the term.

FAQ

Key takeaways

A loan can help you make important purchases or investments, but the true cost goes beyond the advertised interest rate—comparison rates, fees and your repayment term all affect the total you'll pay back. Compare offers using comparison rates rather than headline rates, verify all fees through the Product Disclosure Statement, and ensure you can comfortably meet repayments based on your income and expenses. Consider alternatives like saving or family lending before committing to a loan.
